elements 144 have engagingportions 150 by means of which thelocking elements 144 are engageable with the receivingelement 110, in particular with theflat end region 146 a, remote from theworkpiece 104, of the double T-shapedbeam 124 of the receiving element 110 (see in particularFIGS. 3 and 4 ). - The engaging
portions 150 are movable, towards or away from one another, about the pivot axes 149 by the pivoting of the lockingelements 144. - The
locking device 122 includes anactuating device 152 for moving the engagingportions 150 and for pivoting the lockingelements 144. - The
actuating device 152 includes two actuatingelements 154 that serve to actuate the lockingelements 144. - The
actuating elements 154 are eccentrically mountedactuating elements 154 against the peripheral surface whereof the lockingelements 144 bear by means of actuatingportions 156 of the lockingelements 144. - Because of the eccentric mounting of the
actuating elements 154, the actuatingportions 156 of the lockingelements 144 and thus also the engagingportions 150 of the lockingelements 144 are moved towards or away from one another by a rotation of theactuating elements 154 about arotational axis 158 of theactuating device 152. - To prevent undesired movement of the locking
elements 144, thelocking device 122 includes ablocking device 160. - The
blocking device 160 includes two blockingelements 162. - The blocking
elements 162 are eccentrically mounted blockingelements 162. - The eccentrically mounted blocking
elements 162 are configured to be brought into contact with blockingportions 164 of the lockingelements 144. In particular, the blockingportions 164 are in contact with peripheral surfaces of the blockingelements 162 of theblocking device 160. - As a result of the eccentric mounting of the blocking
elements 162, the positions of the blockingportions 164 of the lockingelements 144 and hence the spacing between the engagingportions 150 of the lockingelements 144 may be influenced. - Both the
actuating device 152 and theblocking device 160 take the form of aneccentric device 166. - In the embodiment of the
locking device 122 illustrated inFIGS. 3 and 4 , theactuating device 152 and theblocking device 160 form a commoneccentric device 166 for actuating the lockingelements 144. - The
actuating elements 154 and the blockingelements 162 are arranged on acommon shaft 168 of thelocking device 122 and are rotatable about the commonrotational axis 158. - In
FIGS. 3 and 4 , theactuating elements 154 and the actuatingportions 156 of the lockingelements 144 are illustrated separately from the blockingelements 162 and the blockingportions 164 of the lockingelements 144. - Depending on the position of the locking
elements 144, however, theactuating elements 154 also function as blockingelements 162, and the blockingelements 162 also function as actuatingelements 154. - Accordingly, the actuating
portions 156 of the lockingelements 144 function as blockingportions 164, and the blockingportions 164 of the lockingelements 144 function as actuatingportions 156. - The
actuating element 154 that is associated with onelocking element 144, and the blockingelement 162 that is also associated with thislocking element 144, are arranged offset from one another, in particular offset by 180°, in respect of rotation about therotational axis 158. On rotation of theactuating elements 154 and the blockingelements 162 about therotational axis 158, for example the eccentrically mounted element that is designated as theactuating element 154 inFIGS. 3 and 4 is thus moved away from the portion of alocking element 144 that is designated as actuatingportion 156 inFIGS. 3 and 4 . At the same time, the associated blockingelement 162 moves towards the blockingportion 164 of thesame locking element 144. As a result, the lockingelement 144 is pivoted about thepivot axis 149. - Preferably, the locking
element 144 always bears against theactuating element 154 by means of theactuating portion 156 and/or always bears against the blockingelement 162 by means of the blockingportion 164. The lockingelement 144 is preferably moved about therotational axis 158 by rotation of theactuating element 154 and the blockingelement 162. - The locking
element 122 includes adrive element 170 by means of which theactuating elements 154 and the blockingelements 162 are rotatable about therotational axis 158. - The locking
elements 144 may be moved, by rotation of thedrive element 170, which is also preferably arranged on thecommon shaft 168, from the open position illustrated inFIG. 3 into the locking position illustrated inFIG. 4 , and/or from the locking position illustrated inFIG. 4 into the open position illustrated inFIG. 3 . - As can be seen in particular from
FIGS. 4 and 5 , in the locking position the lockingelements 144 engage by means of the engagingportions 150 of the lockingelements 144 with the flat end regions 126 a, remote from theworkpiece 104, of the double T-shapedbeam 124 of the receivingelement 110. - Preferably, there is a positively engaging connection between a receiving
element 110 and alocking device 122. - As an additional securing measure, it may be provided for a
locking element 144, in particular one of themovable locking elements 144, to include anadditional securing element 140 that, in the locking position of thelocking device 122 illustrated inFIG. 5 , engages over the flat end region 126 z facing theworkpiece 104. - The conveying
facility 100 described above functions as follows: - A
workpiece 104 that is received by means of two receivingelements 110 is conveyed in the conveyingdirection 106 by means of the conveyingdevice 102. - In particular, the
workpiece 104 is fed to a dip-coating facility (not illustrated). - For coating the
workpiece 104, theworkpiece 104 is first fixed on the movingdevice 116. - For this purpose, the
fastening device 120, which includes the lockingdevices 122, is provided. - For fixing the
workpiece 104 on the movingdevice 116, the receivingelements 110 engage with the lockingdevices 122. - In particular, the receiving
elements 110 are supported on the support surfaces 134 of thelocking device 122 in thepositioning direction 142, and/or thelocking devices 122 are moved towards the receivingelements 110 in thepositioning direction 142. - The locking
devices 122 act in particular on the flat end regions 126 a, remote from theworkpiece 104, of the double T-shapedbeams 124 of the receivingelements 110. - In particular,
immovable locking elements 138 engage withrecesses 136 in the receivingelements 110 in order to fix the receivingelements 110 in respect of the first direction inspace 146 a and the second direction in space 146 b, in relation to thelocking device 122 and hence also in relation to the movingdevice 116. - In principle, it may be provided for each
locking device 122 to include animmovable locking element 138 of this kind. - However, it may also be provided for only
individual locking devices 122 to include animmovable locking element 138 of this kind (see in particularFIG. 2 ). - For locking the receiving
elements 110 in the third direction in space 146 c, thedrive element 170 is rotated for example by an actuator (not illustrated) or a drive motor (not illustrated). - As a result, the eccentrically mounted
actuating elements 154 of theactuating device 152 and the eccentrically mounted blockingelements 162 of theblocking device 160 are also rotated. - Rotation of the
actuating elements 154 and the blockingelements 162 results in pivoting of the lockingelements 144 about the pivot axes 149. - In particular, as a result the locking
elements 144 are moved from the open position illustrated inFIG. 3 into the locking position illustrated inFIG. 4 . - During this, the engaging
portions 150 of the lockingelements 144 are moved towards one another and finally engage behind the flat end regions 126 a, remote from theworkpiece 104, of the receivingelements 110, in the locking position illustrated inFIG. 4 . - As soon as the locking
devices 122 are in the locking position, the receivingelements 110 and theworkpiece 104 arranged thereon may be moved in all directions inspace 146, by means of the movingdevice 116. - In particular, the
workpiece 104 may be moved in the direction ofmovement 118, in particular being rotated about a horizontal axis, in order to be dipped into a dip bath of the dip-coating facility and removed from the dip bath again. - For releasing the connection between the receiving
element 110 and the movingdevice 116, thedrive element 170 is rotated onwards about therotational axis 158, for example by means of the drive motor or actuator (not illustrated). This moves the engagingportions 150 of the lockingelements 144 apart and disengages them from the flat end regions 126 a, remote from theworkpiece 104, of the receivingelements 110. - The receiving
elements 110 and theworkpiece 104 arranged thereon can then be removed from the lockingdevices 122 and conveyed onwards, for example by means of the conveyingdevice 102. - An alternative embodiment of a
fastening device 120, illustrated inFIG. 6 , differs from the first embodiment illustrated inFIGS. 1 to 5 substantially in that the receivingelements 110 are fixed on thelocking devices 122 in respect of the first direction inspace 146 a, in particular the longitudinal direction of the double T-shapedbeams 124 of the receivingelements 110, by means of abar device 172. - The
bar device 172 includes abar 174, which is arranged for example on a flat end region 126 z, facing theworkpiece 104, of the receivingelement 110, and abar receptacle 176, which is arranged for example on alocking device 122. - In particular as a result of a relative movement between the receiving
element 110 and thelocking device 122 in thepositioning direction 142, thebar 174 and thebar receptacle 176 may be engaged with and disengaged from one another. - Otherwise, the embodiment illustrated in
FIG. 6 of thefastening device 120 corresponds, as regards its structure and functioning, to the embodiment illustrated inFIGS. 1 to 5 , so in this respect reference is made to the description thereof above. - An alternative embodiment of the
fastening device 120, illustrated inFIGS. 7 and 8 , differs from the embodiment illustrated inFIGS. 1 to 5 substantially in that theactuating device 152 for actuating the lockingelements 144 includes acam device 178, in particular aguideway device 180. - The locking
elements 144 are formed byscissor elements 182 that are pivotal in relation to one another about a centrally arrangedcommon pivot axis 149. - In this arrangement, the locking
elements 144 each include an engagingportion 150 and a blockingportion 164, wherein the engagingportion 150 and therespective blocking portion 164 of each lockingelement 144 are arranged on mutually opposite sides of thepivot axis 149. - The
scissor elements 182 are arranged to be substantially X-shaped, wherein the engagingportions 150 and the blockingportions 164 are in each case arranged opposite one another. - Between the engaging
portions 150, in particular a receivingelement 110 may be received. - By means of the
actuating device 152, thefastening device 120, in particular thelocking device 122, may be moved from the locking position illustrated inFIG. 7 into the open position illustrated inFIG. 8 , and/or from the open position into the locking position. - For this purpose, the
actuating device 152 includes in particular at least onecam element 184. - The
cam element 184 takes the form for example of abolt 186. - The
cam element 184 may in particular be introduced between the blockingportions 164 of the lockingelements 144 in order to push them apart. - As a result, at the same time the engaging
portions 150 of the lockingelements 144 are moved apart and thus thefastening device 120, in particular thelocking device 122, is moved from the locking position into the open position. - By means of the
cam element 184 in the form of abolt 186, moreover alocking device 188 is unlocked. - The
locking device 188 forms in particular ablocking device 160. - The
locking device 188 includes two blockingelements 162, wherein one blocking element takes the form for example of aprojection 190 and afurther blocking element 162 takes the form of aspring element 192. - The
spring element 192 includes in particular anopening 194 in which theprojection 190 is engageable. - The blocking
elements 162 are arranged on the blockingportions 164 of mutuallydifferent locking elements 144. - In this arrangement, the
spring element 192 for example extends, in the locking position illustrated inFIG. 7 , from the blockingportion 164 of the onelocking element 144 to the blockingportion 164 of thefurther locking element 144 and, in the locking position, engages with theprojection 190. - When the
spring element 192 engages with theprojection 190, thebolting device 188 that forms theblocking device 160 is bolted, with the result that neither the blockingportions 164 nor the engagingportions 150 are movable away from one another. - By means of the
cam element 184, thespring element 192 can be moved away from the oneblocking portion 164 of the onelocking element 144 and disengaged from theprojection 190. - The
locking device 188 is then unlocked. - By providing a suitable shape for the
cam element 184, in particular by forming thecam element 184 as abolt 186, it is possible in a subsequent step to push the blockingportions 164 of the lockingelements 144 apart in order to move thelocking device 122 into the open position. - The
cam element 184 in the form of abolt 186 is in particular an internal cam that acts between the blockingportions 164 of the lockingelements 144. - By means of further cam elements 184 (not illustrated) that form for example an external cam, the
locking device 122 may preferably be moved from the open position illustrated inFIG. 8 back into the locking position illustrated inFIG. 7 . - As a result of this, the
spring element 192, which is formed for example from spring steel, comes back into engagement with theprojection 190, preferably automatically, with the result that thelocking device 188 is locked automatically. - Otherwise, the embodiment illustrated in
FIGS. 7 and 8 of thefastening device 120 corresponds, as regards its structure and functioning, to the embodiment illustrated inFIGS. 1 to 5 , so in this respect reference is made to the description thereof above. - Because, in all the embodiments of the
fastening device 120, a receivingelement 110 for receiving theworkpiece 104 and alocking device 122 for releasably fixing the receivingelement 110 on the movingdevice 116 are provided, thefastening device 120 has a small space requirement and at once enables secure fastening of theworkpiece 104 to the movingdevice 116.
